A20's to A30's
Let me start by being honest; Amazon's not letting me review the new A30's here but here's my review of both A20's and the new A30's. This is posted on SoundCore's site as well: First a couple of back story statements: Amazon is now not taking reviews of the A30's unless the buds are purchased through them and since I was part of the Early Bird KickStarter and got them directly from SoundCore I couldn't do a review there (where most of the reviews are posted and viewed). It seemed that the majority of reviews on Amazon were from first time SoundCore users. I've had six months of A20 use and the same amount of time communicating with SoundCore's Support Team and Tech Team so I have some viewpoints on that. As a note I was a Bose SleepBud user for three years and experienced all the down sides of their difficulties with battery, range and software glitches that eventually drove them to decide to discontinue the product. Here's my take going from the plus side to the somewhat negative side: For those of us who had good experiences with the A20's the shift to the A30's is far easier than it would be for a first time user. The app layout is similar with some changes that take into account the ANC tech and the ability to store more than one "Land" sleep sound whether white noise or snore blocking. While this seems a little clunky unless you want to continually change sleep sounds night by night I don't see any issue with this. The setup is quite easy as were the A20's and pairing whether using the app or the Bluetooth setting is simple. The app's navigation is similar to the A20's with some needed additions to the Sound Scape variety for pre-sleep. As with the A20's the range of the buds from a phone is excellent so if you have to head to a distant bathroom or elsewhere the long range really helps. The whole reason for switching from the A20's to the A30's was the addition of ANC to the product. The A30 bud is slightly larger than the A20 but certainly still low profile and comfortable and permits side sleeping without issues. The reviews mentioning the lack of sensitivity with the touch adjustments for sound level and switching from Bluetooth to Sleep mode may be due to the need to contact the bud DIRECTLY on the flat face rather than even slightly off center. A big complaint from reviewers on both A20's and A30's is the sudden transition from Bluetooth mode to Sleep mode that's jarring and tends to wake you up with the software detects sleep. I think this is being addressed but is a definite downside for both devices. Again, similar to the A20's. I've communicated some of my concerns about the transition from A20's to A30's directly to SoundCore's teams but my chief complaint is the difficulty in SoundCore's verbiage on the directions for the products. Simple is good and my experience with both the ear buds as well as other SoundCore speakers is that their directions use quite confusing wording and in general need to be far more clear and use simple statements that don't require trying to figure out what the terminology means and what they're intended to do. Finally, I've read reviews that are critical of the ANC function in terms of how much noise the A30's is blocked out. My experience is that the ANC is not nearly as effective as either over the ear cans or competitors' like Bose's noise cancelling but in such a small package that's very comfortable for sleep positions you're not going to fit total ANC in the bud. It does reduce background noise but is certainly not capable of true ANC as of right now. Now for the positive; In the six months I've dealt directly with SoundCore their Support and Tech teams are excellent. In a business that normally does not have the ability to directly contact the manufacturer by phone the Tech team is accessible and very helpful. SoundCore Support is email only but VERY responsive in a short time frame and is very patient and helpful. I know this may seem a side issue but for anyone that's experienced product and setup direction issues being able to get quick responses and tech guidance is a game changer. SoundCore is pushing hard on brands like Bose's product placement and is now in both Verizon stores as well As Costco. With the added customers i'm hoping that the customer service gets expanded and can keep up. I know that SoundCore is working on software updates and some technical tweaks and that should help but right now not sure that switching from the A20's to the much pricier A30's is necessary. For first time SoundCore customers the A30's function well and have some features that make it worth the bucks with the proviso that SoundCore will continue the software and direction improvement.

Good sleep earbuds, but Soundcore will brick them with firmware updates, so beware
I have been an Anker Soundcore Sleep Earbuds customer since the beginning. I purchased the original A10, then backed the A20 in the Kickstarter and purchased a second pair (for my wife) from Amazon. I also backed and received the A30 on Kickstarter and are using those presently. So, I don't give a review like this one lightly. I got my original A20 earbuds back in May 2024 and the 2nd pair in Jan 2025. Honestly, they are awesome. Sound quality is great, periodic cleaning kept them working well, they mask noise well and the battery life was perfectly fine until.... A month or so ago, my A20's got the 1.57 firmware update from Soundcore. I didn't think anything of it at the time, but the right earbud just started refusing to charge above 30%. It would charge from 0% to 30% just fine, indicating it had good contact with the pogo pins. But it simply would not charge over 30%, ever. The left earbud charged perfectly fine to 100% every time. I did some research and it turns out many others are experiencing the same issue, specific to the 1.57 firmware update. Apparently, that firmware has a known issue where it messes up the battery calibration of the right earbud and causes this exact problem. So, in short, Soundcore pushed a firmware update to my A20 earbuds and in the process made them unusable. You might think "Well, they're in the 18 month warranty, just get them replaced". I did reach out to support, and they agreed to replace the earbuds, but what happens when Soundcore pushes out a firmware update that breaks the earbuds when they are just out of warranty? If the warranty is 18 months, and Soundcore can break your device outside of the warranty at any time, this means that the device has an 18 month lifespan. So, if you are going to purchase these be aware that they should be considered disposable and you probably won't get more than 18 months of usage out of them given the above. UPDATE: 2025-12-20 Soundcore sent me replacement A20's for the ones that they damaged with their 1.57 firmware update. These new A20 sleep buds came with a much higher revision of the firmware 03.22. So, it looks like the firmware now skips from 1.50 to 03.22, as Soundcore definitely has pulled 1.57 off their servers (since it broke so many customers' A20s). But... the replacement pair Soundcore sent me were defective. The right earbud consistently discharges at more than 2x the left earbud. So for example, after 7 hours of Sleep Mode white noise playback, the left ear bud would be at 70% while the right ear bud was at 30%. I am continuing to see if I can get Soundcore to actually send me a functioning replacement for the sleep buds they broke. We'll see what happens... UPDATE: 2025-12-29 Soundcore sent me a second replacement for the defective A20's that they sent as the first replacement for the A20's they bricked with the 1.57 firmware update. So, this is now the third pair of A20s... This pair appears to work correctly, and the right and left earbud discharge battery at the same rate and look like they will achieve 12-14 hours of playback at 50% volume in Sleep Mode. So... after several weeks of back and forth, and multiple pairs of bricked or defective earbuds, it looks like I have a properly working pair again. Support was very helpful about all of this, and I found them receptive to all of the issues I was experiencing, so I don't want to be disparaging of Soundcore support at all here. In general, I've found them good to work with. But... I think the quality control of the Soundcore products is not great. I had battery discharge issues with my original A10 earbuds, and went through a similar replacement dance with those as well. It seems like Soundcore's sleepbuds are prone to battery issues very frequently, since I've now seen issues with uneven battery discharge in 4 separate pairs of A10 and A20 earbuds. My wife's A20 sleepbuds are still on the 1.50 firmware, as the 1.57 firmware has been pulled by Soundcore. I asked support about this and they confirmed that there were multiple hardware revisions of the A20's, and the replacement A20's that I got (which are on the 03.22 firmware) are a later hardware revision than the A20s that were on the 1.50 and 1.57 firmware. Support left it very ambiguous as to whether or not hardware with the 1.50 line of firmware would even continue to get firmware updates, or if that hardware revision has been effectively abandoned by Soundcore. If you are going to purchase these, you need to make sure that the firmware is the 03.22 line, and NOT the 1.50/1.57 line, since that means you have an older revision of the hardware.

W tych słuchawkach można naprawdę wygodnie leżeć na boku. Nie spodziewałem się tego, mimo obejrzanych przeze mnie recenzji, bo nawet małe zatyczki do uszu, które posiadam, wywierają presję na ucho. Tutaj prawie tego nie ma. Wreszcie mogę wygodnie słuchać audiobooków przed snem! W zestawie, oprócz standardowych gumek, są też takie przepuszczające powietrze (i dźwięk). Te są nawet wygodniejsze od tych tradycyjnych, chociaż dźwięk traci nieco na jakości (jest o wiele mniej basu). Do podcastów czy audiobooków jednak basy nie są aż tak potrzebne, liczy się wygoda. :) Gęsty stuknięciami w słuchawkę są bardzo przydatne, choć trzeba się do nich trochę przyzwyczaić (musiałem się nauczyć w nie stukać mocniej niż się spodziewałem). Ogółem, jestem bardzo zadowolony z zakupu i polecam te słuchawki każdemu, kto lubi sobie czegoś posłuchać przed snem.

I have used these headphones every day since I got them. They are comfortable enough to sleep in, which is a priority for me because my husbands snoring keeps me awake. They are easy to use, I love the case. Would replace immediately if I lost them

Hago esta reseña viniendo de unos Anker Soundcore A10 (el modelo del año pasado) que si se les podía achacar algo era la poca duración de batería en modo "bluetooth". Sin duda, este nuevo modelo corrige los problemas de la versión anterior. Será inevitable comparar ambos modelos en esta reseña (A10 y A20). Tengo acúfenos (tinnitus) y dormir sin algo que enmascare esos molestos ruidos es bastante complicado. Habiendo pasado por los Bose Sleepbuds, Soundcore A10 y como me ha crecido barba esperando los Ozlo que nunca llegan a Europa (iba a ser mayo, luego se suponía que julio, ahora dicen que a finales de julio), decidí probar estos A20 viendo la buena crítica en cuanto a batería. Llevo algo más de un mes usándolos y creo que es tiempo suficiente para poder opinar sobre ellos. CAJA: Los auriculares vienen en una caja de pequeño tamaño, ideales para llevar de viaje. Se sujetan a la caja magnéticamente. Decir que la forma de colocarse no es la más natural, y los primeros días, cuando te despiertas y los quieres guardar en la caja, no encuentras cómo deben colocarse (entre dormido que estás, no te enteras mucho). Una vez colocados en la caja, se empiezan a cargar. Se puede ver el estado de carga mediante tres led en la parte frontal. La caja en sí se abre deslizándose hacia arriba y en mi caso tiene tendencia a resbalarse de las manos. AURICULARES: Los auriculares son suaves, ligeros, pequeños. Se ajustan perfectamente a cada individuo. El fabricante incluye varias gomas para que a prácticamente todo el mundo le encajen a la perfección. Decir que se incluyen muchos tipos de pad de silicona muy suave y blandita (realmente se nota super esponjosa) y al colocarlas en tus oídos, no notas dolor, presión o nada parecido. Me encanta que casi ni se nota que los llevas puestos. Es posible que haya que combinar un pad de tamaño distinto para cada oído, por lo que recomiendo no precipitarse e ir probando distintas combinaciones hasta encontrar con el indicado. En mi caso, no tuve que hacer ningún cambio y estoy usando los que vienen por defecto. Sin embargo, estuve probando un rato. Como digo, los auriculares son ligeros, mucho. Puedes dormir perfectamente de lado que no sobresalen y no duelen (a veces con el modelo anterior, los A10, me despertaba con algo de dolor y presión). Esto no ocurre con los A20, la silicona es tan suave! MODOS DE USO: Los auriculares tienen dos modos de uso: Bluetooth, para lo que necesitaremos el móvil cerca, y el modo "autónomo" donde no necesitaremos el móvil y los auriculares reproducirán un sonido en bucle mientras los llevemos puestos. En este último modo, el sonido se carga en los auriculares y no necesitaremos el móvil cerca. Además, la batería durará mucho más tiempo. El modo Bluetooth por contra, reproducirá lo que estemos escuchando (música, podcast, ... ). Por contra, este modo reduce bastante la duración de la batería. En este punto quiero decir que si bien el modelo anterior la batería no duraba más de 4 horas en modo Bluetooth, en estos nuevo A20, siempre me despierto y queda alrededor de un 15% de batería (decir que duermo sobre las 7 horas) por lo que creo que alcanzarán unas 8h tranquilamente. Lo escucho a volumen bajo, bastante bajo, lo suficiente para camuflar los sonidos que escucho por culpa de mi tinnitus. Otro punto a tener en cuenta es que la biblioteca de sonidos que se ha incluido, además de ser mucho más amplia (tenemos todo tipo de ruidos: ruido blanco, ruido rosa, sonidos de olas, arpas, ...) son de mucha más calidad. En los A10 era un sonido de 20 segundos que se repetía en bucle y se notaba mucho cuando se terminaba y empezaba de nuevo (lo cual, ponía un poco nervioso dicho sea de paso). En estos A20, lo he probado y los sonidos son más largos y por lo menos en los que he probado, no escucho ese cambio. El modo que uso yo es el Bluetooth. Cada noche escucho Calm, donde hay melodías infinitas o playlists de 8 horas. Según lo que me apetezca, reproduzco una u otra. Voy cambiando, así no me aburro siempre de escuchar lo mismo. APLICACIÓN MÓVIL: La aplicación móvil ha sido rediseñada para estos A20, de manera que es mucho más completa. Mantiene los dos modos que he mencionado antes (Bluetooth y autónomo) pero se han añadido dos cosas: análisis de sueño y playlists para modo autónomo. Empezaré por este último, pues se pueden añadir varios sonidos de los incluidos en la aplicación a modo de playlist. No lo he probado pero he visto que lo permite. Decir que tampoco se pueden subir sonidos nuestros, es decir, si queremos usar este modo, tendremos que usar los sonidos que se incluyen en la aplicación únicamente. Por otro lado, el análisis de sueño (otro más, junto con el del Apple Watch y el RingConn) te indica las horas de sueño, tiempo de sueño profundo, etc. Un detalle curioso es el número de veces que nos damos la vuelta y el porcentaje de tiempo que hemos dormido de cada lado (derecho o izquierdo). No deja de ser curioso.Mediante esta app, también podremos actualizar la firmware de los auriculares cuando haya uno nuevo. En mi caso han llegado 2 actualizaciones. BATERÍA: Aunque lo he comentado antes, una de las cosas que más me ha gustado de estos A20 y que sin duda son una gran mejora respecto del modelo anterior, es la duración de la batería. Ahora puedo escuchar durante toda la noche lo que yo quiera, sin tener que ir a los sonidos incluidos en el dispositivo (y que insisto, han mejorado mucho). Creo que los reviews que he leído que se alcanzan 9 horas con la batería son bastante reales. Es cierto que en los A10, al cabo de unos meses la batería se degradaba con bastante facilidad, veremos qué tal va en estos. Decir también que la caja se carga mediante USB-C (no dispone de carga inalámbrica). CANCELACIÓN DE SONIDO: No, estos auriculares no disponen de cancelación de sonido. Sí que es verdad, que debido al diseño de las almohadillas (pads) puede haber una falsa cancelación de sonido. De hecho, se incluyen algunas almohadillas con un pequeño orificio que deja pasar el sonido, de manera que si tenemos niños, bebés que pueden llamarnos por la noche, los escuchemos (bueno, a priori, porque yo cuando duermo ya se puede caer el mundo). En cualquier caso, el aislamiento es bastante notable. Yo vivo en una calle con bastante tráfico y debajo hay un restaurante y con los auriculares, la melodía y demás, no escucho ni los coches ni la gente al salir del restaurante. VALORACIÓN: Sobresaliente. Creo que hoy por hoy son los auriculares perfectos para dormir. Ya digo que debido a mi problema he pasado por muchas marcas distintas (Hoomband, que como me muevo mucho se mueve la cinta, Bose Sleepbuds que por el precio que tenían acabaron siendo un fracaso a nivel de batería, Anker Sleep A10 que fueron un primer paso para entrar en este mundo y estos A20 que son perfectos). Me arrepiento de haber comprado los Ozlo, que posiblemente sean un muy buen producto pero a nivel de precio, nada que ver con estos A20, y eso que tampoco son baratos. De hecho, un factor negativo de estos A20 es el precio, creo que es algo elevado. Sin embargo, en mi caso, es el precio que hay que pagar para dormir bien y bien invertido está. Sin duda un producto muy recomendable!!

Ottime cuffie, se utilizzate per dormire. Presentano due modalità di connessione, Bluetooth e Sleep: Bluetooth: si collega al telefono e riproduce l'audio dal telefono o dall'applicazione. Sleep: riproduce audio precaricato dalle cuffie e non necessità di telefono. Ovviamente la modalità Sleep cossente una durata delle batteria superiore. Sono in grado di rilevare quando ci si addormenta e quindi si spengono di conseguenza ma possono durare le 8h di sonno anche senza la funzione attiva. L'app Soundcore è molto chiara ed intuitiva, è possibile creare degli audio personalizzati da caricare sulle cuffie per la modalità Sleep, selezionando gli effetti ed i rumori, regolandoli per intensità tramite un equalizzatore. Il prezzo è elevato se si paragonano a cuffie di altre marche che si utlizzano per ascoltare musica o video. Questa cuffie sono ottime per dormire in quanto sottili, con una buona scelta di membrane che isolano (non hanno l'ANC, la cancellazione è solo fisica tramite silicone), non danno fastidio se si dorme sul lato. Per ascoltare musica ci sono altri prodotti, ad un costo inferiore, che suonano meglio: non è l'ascoltare musica il loro scopo. Vanno spesso in offerta a 110€ un buon prezzo se si cerca quello per cui sono state pensate.

Très bon produit (malgré la mise à jour qui a changé quelques paramètres qui étaient bien pratiques) et super service après-vente rapide et efficace ! Màj 17/6: pas facile à paramétrer pour trouver les bons sons. Voici le fruit de mes recherches si ça peut aider: Le principe de base: bien choisir les embouts bloquant le bruit, éventuellement des embouts différents d'une oreille à l'autre et analyser le type de bruit (grave, aigu) qui vous gêne. - le bruit blanc bloque toutes sortes de fréquences (basses comme aiguës) - le brun bloque les fréquences basses. Le rouge est similaire - le rose correspond à des bruits de pluie, de vagues... Et l'intensité du son diminue quand la fréquence augmente - le gris est équivalent au rose, sauf que l'intensité reste identique sur toutes les fréquences - le vert sert à la relaxation -le violet permet de bloquer les fréquences aiguës. - si ce sont des ronflements que vous essayez de bloquer, c'est très variable d'une personne à l'autre, mais ça varie entre 25 et 110 hertz.
